FIGS. 1A to 1C illustrate situations that an electronic device displays a user interface on a display, according to an embodiment of the present disclosure.

Referring to FIG. 1A, an electronic device 100 may support a wake-up mode of allowing a user to intensively use functions of the electronic device 100 and a sleep mode of waiting for the use of the electronic device 100 by the user.

The electronic device 100 may operate under sufficient power (e.g., power necessary for all pixels included in the display to express color having preset gradation) received from a battery such that various hardware modules and/or software modules included in the electronic device 100 sufficiently perform the functions thereof in the wake-up mode. For example, the display may receive sufficient power in the wake-up mode to provide various pieces of content required from a user, and a processor included in the electronic device 100 may provide various functions based on sufficiently supplied power.

The electronic device 100 may operate under the minimum power to deactivate the various hardware modules and/or software modules included in the electronic device 100 or perform only specified limited functions in the sleep mode. For example, a camera module may be deactivated in a function of capturing a photo and a moving picture in the case of switching to the sleep mode. In addition, the processor may be configured to execute only a limited function of an application program in the case of switching to the sleep mode. Accordingly, since information processing or computations are restricted depending on hardware modules and/or software modules, battery lifetime of the electronic device 100 may be enhanced.

According to an embodiment, the electronic device 100 may display preset information (e.g., time information, a date, weather, or the like) on a display 10 in the sleep mode. The electronic device 100 may display multiple pieces of preset information in specified color using preset pixels and may set remaining pixels to be in specified another color (e.g., black color). For example, in the case that the display 10 includes an organic light emitting diode (OLED) panel, the remaining pixels may be turned off.

Such a display output manner may be referred to as “always on display (AOD)” in that useful information is always provided. In addition, the display output manner may be referred to as “self-display” in terms of displaying on a display through the intrinsic operation of a display driver integrated circuit (DDI) without intervention of the processor.

To implement AOD functions, the DDI may at least include a graphic random-access memory (GRAM) and a control module. The GRAM may be referred to as, for example, “frame buffer” or “line buffer”. The GRAM may store image data corresponding to the above-described preset information displayed in the sleep mode. The control module may select a part of the image data stored in the GRAM and may control the selected part to be output to a specified position of the display 10. The control module may be referred to as “control circuit”.

As described above, the electronic device 100 of FIGS. 1A to 1C may be in the wake-up mode or the sleep mode and may display various pieces of information (e.g., content, a user interface, or the like) on the display 10 according to states of the electronic device 100. For example, the electronic device 100 may display a user interface or content using an image, which is stored in a memory by the processor, in the wake-up mode. In addition, the electronic device 100 may display a user interface or content using an image, which is stored in the GRAM included in the DDI, in the sleep mode.

Referring to FIGS. 1B and 1C, the electronic device 100 may display a user interface 20 and/or content 30 on one region of the display 10. When the electronic device 100 receives a signal generated from the outside of the electronic device 100 or when an event occurs inside the electronic device 100, the electronic device 100 may display, on the display 10, the user interface 20, which is used for notifying the reception of the signal or the occurrence of the event to a user, or content created based on the content of the signal or the content of the event.

According to an embodiment, the event occurring inside the electronic device 100 may include, for example, a preset alarm, schedule notification, an internal system state change, or the like. The signal received from the outside of the electronic device 100 may include, for example, a text message, a call, application update information, or social media updates.

The user interface 20 and the content 30 may be simultaneously or sequentially displayed. The sequence and the position to display the content 30 and the user interface 20 may be varied depending on the type of the content 30 and the state (e.g., the wake-up mode, the sleep mode, or the like) of the electronic device 100. For example, the electronic device 100 may simultaneously display the content 30 and the user interface 20. The electronic device 100 may display the user interface 20 after first displaying the content 30. Inversely, the electronic device 100 may display the content 30 after first displaying the user interface 20.

According to an embodiment, the user interface 20 may be displayed along an edge region of the display 10. The edge region may correspond to one part of the display 10 adjacent to a housing 40 of the electronic device 100. For example, the electronic device 100 may include a first edge region 11, a second edge region 12, a third edge region 13, and a fourth edge region 14. The first to third edge regions 11, 12, 13, and 14 may refer to regions formed by a specific width toward an inner part of the display 10 from edges of the display 10.

According to an embodiment, the user interface 20 may show an effect such as that the user interface 20 moves along the edge region of the display 10. The user interface 20 may include a starting point 21 and an ending point 23. Additionally, the user interface 20 may further include a progress direction guide 22.

The user interface 20 may have the shape of a line or a face. The user interface 20 may be expressed with brightness higher than surrounding brightness. The user interface 20 may have a variable length. The starting point 21 may have various shapes such as a circle, a rectangle, a triangle, an arrow shape, or the like. The ending point 23 may have, for example, a gradation effect. The user interface 20 may be understood as a kind of a graphic effect present in an edge region of the display 10.

Referring to FIGS. 1B and 1C, the electronic device 100 may change the position that the user interface 20 is displayed on the display 10. For example, the electronic device 100 may display the ending point 23 of the user interface 20 on the first edge region 11 and may display the starting point 21 of the user interface 20 on the second edge region 12. In addition, the electronic device 100 may extend the length of the user interface 20 to display the starting point 21 of the user interface 20 on the fourth edge region 14 and to display the ending point 23 of the user interface 20 on the first edge region 11. Accordingly, the electronic device 100 may implement an animation effect such as that of the user interface 20 moving along the edge region of the display 10.

The user interface 20 may include information on various attributes. The information on the attributes may include, for example, the form (e.g., a face, a line, or the like) of the user interface 20, color (e.g., a hue, brightness, saturation, or a color effect (a gradation effect, a blinking effect, or the like) of the user interface 20, the movement (e.g., movement using the control of a pixel value, movement by continuous display of a plurality of images) of the user interface 20, a moving direction of the user interface 20, the moving speed of the user interface 20, time that the user interface 20 is displayed, time taken until the user interface 20 is displayed again after the user interface 20 is displayed on the full part of the display, or the starting and ending points 21 and 23 of the user interface 20.

According to an embodiment, the electronic device 100 may display the user interface 20 in preset color. However, the color of the user interface 20 may be determined according to various criteria. For example, the electronic device 100 may determine the color of the user interface 20 based on information on an application which created the content displayed on the display 10. In this case, the application may specify the color. For example, in the case that a dialing application displays dials in green color, the electronic device 100 may display the user interface 20 in green color when generating a message about a missed call. If a message about another missed call is generated, the electronic device 100 may display the user interface 20 in color complementary to green color.

The color determination of the user interface 20 depending on applications is limited thereto. For example, a user may select desired color between color of the application, which is basically provided by the electronic device 100, and color provided by the application.

The electronic device 100 may set the color of the user interface 20 to the same color as that of a light emitting diode (LED) (not illustrated), which is included in the electronic device 100, or to the color selected by the user.

According to another embodiment, the electronic device 100 may display the user interface 20 by adjusting a hue, brightness, and saturation belonging to the color expressed for the user interface 20 or by adding an image effect (e.g., a gradation effect, a blinking effect, or the like) to the user interface 20.

As described above, the electronic device 100 may provide various notification effects for a user using the user interface 20 displayed on the edge region of the display 10.

FIG. 2 is a schematic block diagram of the electronic device, according to an embodiment of the present disclosure.

Referring to FIG. 2, the electronic device 100 may include a display 210, a processor 220 (e.g., at least one processor), a communication circuit 230, and a memory 240. Some of elements of the electronic device 100, which are illustrated in FIG. 2, may be omitted or other elements, which are not illustrated in FIG. 2, may be added. For example, the electronic device 100 may include elements of one or more sensors, a sensor module (e.g., a gesture sensor, a gyro sensor, or the like), a power supply unit, or the like.

The display 210 may include, for example, a liquid crystal display (LCD), a light-emitting diode (LED) display, an organic LED (OLED) display, a microelectromechanical systems (MEMS) display, or an electronic paper display. The display 210 may include a touch screen and may receive, for example, a touch, gesture, proximity, or hovering input using an electronic pen or a part of a user's body.

According to an embodiment, the display 210 may include a touch sensor, a pressure sensor and/or a fingerprint sensor. For example, if the touch sensor is included, the display 210 may be referred to as “touchscreen display”.

According to an embodiment, the display 210 may receive an image driving signal from the DDI. The display 210 may display various user interfaces and various pieces of content, based on the image driving signal. For example, the display 210 may display a user interface on at least a part of an edge region of the display 210 and may display content in one region of the display 210.

The processor 220 may, for example, control a plurality of hardware or software elements connected to the processor 220 and may perform various data processing and arithmetic operations, by running an operating system (OS) or an application program.

According to an embodiment, the processor 220 may control the display 210 to display messages, which are generated from various applications installed in the electronic device 100, on the display 210. In addition, the processor 220 may control the display 210 to display content, which corresponds to a signal received from the outside through the communication circuit 230, on the display 210 in the form of a message.

The processor 220 may display the user interface based on an event occurring inside the electronic device 100 or a signal generated from the outside. According to an embodiment, the processor 220 may change the form of displaying the user interface based on the type of an application generating the signal or the event, or the content included in the signal or the event.

The communication circuit 230 may include, for example, a cellular module, a wireless fidelity (Wi-Fi) module, a Bluetooth (BT) module, a radio frequency (RF) module, or the like. The communication circuit 230 may form a network together with another electronic device under the control of the processor 220.

According to an embodiment, the communication circuit 230 may receive a signal from an external electronic device under the control of the processor 220. In addition, the communication circuit 230 may transmit information on the state changes of applications installed in the electronic device 100 to the external electronic device.

According to various embodiments, the memory 240 may store instructions or data associated with operations of elements included in the electronic device 100. For example, the memory 240 may store instructions that, when executed, cause the processor 220 to perform various operations disclosed in the present disclosure.

FIGS. 3A to 3C illustrate display structures provided in various forms and installed in the electronic device, according to an embodiment of the present disclosure.

According to an embodiment, a display may have various forms. For example, a flat-panel display may be included in the form of a flat surface on one surface of the electronic device 100. In the case of the flat-panel display, as described with reference to FIGS. 1A to 1C, the electronic device 100 may display a user interface on an edge region of the display (e.g., the display 10 of FIGS. 1A to 1C). In addition, a curved display may be disposed throughout one surface (e.g., a front surface) of the electronic device 100, a surface (e.g., a rear surface) facing a direction opposite to a direction that the one surface faces, and a side surface between the one surface (e.g., the front surface) and the surface (e.g., the rear surface). In the case of the curved display, the electronic device 100 may display a user interface (e.g., a user interface of FIGS. 1 A to 1C) on a part having a curved surface.

Referring to FIGS. 3A to 3C, the electronic device 100 may include a display which is curved in four surfaces (top, bottom, left, and right surfaces). A display 310 curved in four surfaces may include a first surface 31, a second surface 32, a third surface 33, and a fourth surface 34 corresponding to four surfaces of the electronic device 100. Accordingly, the curved display 310 may surround side surface of the electronic device together with the four surfaces of the electronic device 100.

According to an embodiment, in the case that the electronic device 100 includes the curved display 310, the electronic device 100 may display a user interface (e.g., the user interface 20 of FIGS. 1A to 1C), which is described above with reference to FIGS. 1A to 1C, on the first surface 31, the second surface 32, the third surface 33, or the fourth surface 34 included in the curved display 310. However, the present disclosure is not limited thereto. For example, the electronic device 100 may display the user interface 20 on the second surface 32 or the fourth surface 34, or may display the user interface (e.g., the user interface 20 of FIGS. 1A to 1C) on long and narrow flat regions of the curved display 310, which are adjacent to the first surface 31 and the third surface 33. In other words, the electronic device 100 may display the user interface (e.g., the user interface 20 of FIGS. 1A to 1C) in various configurations.

Referring to FIG. 3A, the curved display 310 may be rounded in a region corresponding to a corner part making contact with side surfaces of the electronic device 100. The electronic device 100 including the curved display 310 illustrated in FIG. 3A may employ corner parts of the electronic device 100 as display regions.

Referring to FIG. 3B, the curved display 310 may be in the form of a four-surface cross display. According to an embodiment, the curved display 310 may not include corner parts making contact with side surfaces of the curved display 310.

Referring to FIG. 3C, the curved display 310 may be in the form of a four-sided cross display. In this case, the curved display 310 may be formed such that surfaces of the curved display 310, which correspond to the corner making contact with the side surfaces of the electronic device 100, are linked to each other while forming an angle of about 90°. In this case, a point 39, at which the surfaces of the curved display 310 meet together, may include a structure capable of protecting the curved display 310 from external impact.

FIGS. 4A to 4D illustrate various situations that the user interface is displayed in the electronic device, according to an embodiment of the present disclosure.

Referring to object (a) of FIG. 4A, the electronic device 100 may display the user interface 20 on the first edge region 11 of the display 10. The edge region may be one part of the display 10 adjacent to the housing of the electronic device 100, as described with reference to FIGS. 1A to 1C. Accordingly, in the case that the display 10 has a curved surface, the edge region may be a part having a curved surface.

The displaying of the user interface 20 may be started from the central part of the first edge region 11 or a specific point of the first edge region 11. The user interface 20 may include the starting point 21 and the ending point 23.

Referring to object (b) of FIG. 4A, the electronic device 100 may display the user interface 20 on the first edge region 11 and the second edge region 12 of the display 10.
